It is very true that I have said that I considered Napoleon's presence in the field equal to forty thousand men in the balance. This is a very loose way of talking; but the idea is a very different one from that of his presence at a battle being equal to a reinforcement of forty thousand men.
Arthur Wellesley, (1769 - 1852)
